CARBURETER.

To all wtom t may concern:

Be it known that I, PHILIP CUTHBERT PHIPPEN BOOTY, subject of the King of Great Britain, residing at No. 15 Punt road, lVindsor, in the State of Victoria, Australia, have invented certain new and useful Improvements in Carbureters, of which the following is a specilication. y

This invention relates to a carbureter for charging atmospheric air with the vapor of petrol or other volatile hydrocarbons.

The object of the invention is to provide an improved carbureter whereby the mixture is automatically supplied according to the take oli of the mixture, and whereby the air and petrol or other volatile liydrocarbons are -miXed in predetermined and approved proportions and irrespective of the amount of the take olf of the mixture.

The construction and use of the device will be explained with the aid of the attached drawings in which;

Figure 1 shows a sectional elevation and Fig. 2 a plan thereof. Fig. 3 a plan of the gas bell. Fig. 1l a plan of gas valve cone. Fig. 5 a plan of gas valve cone support. Fig. 6 a sectional plan of petrol valve ring. Fig. 7 a plan of petrol valve chamber. Fig. 8 an enlarged detail section of the upperA portion of the valve chamber. Fig. 9 a partial plan of a section through the petrol valve stem.

ln the said drawing l designates the cai'- bureter casing having the concentric well 2 for holding the glycerin, water or other sealing agent and into which dips the vinverted and floating bell 3 having the central support a carrying the valve tube 5 and petrol valve 6. The valve tube ,54 has an internal flange at its lower end 5a to lt the larger Iend of the valve cone 7.

The petrol valve 6 Ais supported by the floating bell 3 and is kept in a central position by passing through the valve cone 7 and the petrol valve rin 8. The petrol valve 6 consists of a. vertical rod of metal provided witha tapering groove or slot 61v orether means for gradually varying the sectional area of such portion of its length sliding through the petrol valve ring 8. The lower portion terminates in a cone to suit the petrol valve seat 9.

The valve cone 7 is supported in a central position by the stationary valve cone .sup-

port 10, into the lower portion 10a of which the petrol Hows as hereinafter described.

Application filed April 20, 1915. Serial No. 22,668.

To such portion 10a is litted a pipe 11 terminating in a drip point 12 from whence the petrol falls into the carbureting chamber The gas valve cone support 10 is provided with the slots or openings 10b in order that the pressure within the casing 13 may be freely maintained around the top of the petrol valve ring 8.

The casing 13 carries a bracket 14 having a splitor spring eye or other 'adjustable clamping device 15 which adjstably supports the petrol float chamber 17. By means of this construction the vertical position of the petrol float chamber 17 is regulated so as to govern the(Y pressure. at which the petrol is supplied by means of the feed pipe 18 and the connection 19 to the petrol chamber 19a. The said petrol float chamber 17 is supplied from a v petrol tank as usual through the filter 20a and the pipe 20.

The casing 13 is provided with two pipes the casing 13 the lioat chamber 17 and the petrol tank (not shown in the drawings).

he casing `is also provided with the sight feed glass 25 by means of which the flow of petrol from the drip point l2 into the carbureting chamber may readily be observed.

The action of the appliance is automatic and is as follows z-In the drawing the bell 3 is shown in its lowermost or closed down position with the flanged end of the tube 5 fitting the large end of the cone 7 and the coned end of the petrpl valve 6 resting on its seat 9 and the tapering grooved portion Ga below the petrol valve ring 8 which positions are maintained as long as there is no take olf of carbureted air through the valve cone 7 that the requisite area is provided by the annular space formed between the flanged end 5a of the tube 5 and the cone 7 to allow carbureted air to pass through and in to the upper chamber 24 to restablish the pressure and supply the amount of carbureted air called for through the pipe 23. The rising of the bell carries with it the petrol valve 6 which ,-valve and a petrol valve formed with a` leaving its seat 9 allows the petrol to flow in an upward direction into the upper portion of same and thence between the slot 6a of the valve 6 and the ring S at a rate proportionate to the height to which it is lifted. Through thelower portion lOof the cone support 10 the petrol passes to the pipe 1l and is fed through the dripv point 1:?l into the mixing chamber. In the latter chamber the dripping petrol meets the incoming air whereby carbureted air of a fixed quality is generated predetermined by the proportionate areas of the annular space formed by the flange 5a on the tube 5 and the cone 7 and the area of the groove or slot 6a in the petrol valve when opposite the ring 8 through which it passes. l

It will be apparent that the greater 'the consumption of carbureted air the higher the bell will rise and consequently the wider the petrol valve will be opened and the greater thefeed of petrol to the carbnreting chamber all in proportion to the amount of carbureted air passing to the delivery pipe.

I claim lfIn a carbureter provided with a carbureted air chamber anda floating bell, a valve device consisting of a tapered'gas tapered groove each of said valves being automatically controlled by said bell.

In a carbureter provided with a carbureted air chamber and a floating bell, a petrol control valve formed with a tapered groove and connected with said bell and a ring in which said valve is slidably mounted.

3. In a carbureter provided with a. carbureted air chamber and a floating bell, a i

y drip point.

41. In a carbureter provided with a carbureted air chamber and a floating bell, a

carbureting chamber, a mixture valve con.

sisting of a depending tube on said bell formed with an inturned flange at its lower end and a stationary cone over which said .end is fitted, and a valve for admitting -petrol to said carbureting chamber.

5. In a carbureter provided with a carbureted air chamber and a floating bell, a petrol control valve consisting of a vertical rod attached to said bell. and formed at the lower portion with a coned end and with a tapered groove, a carbureting chamber, a ring through which said `lower portion passes to supply petrol thereto and a m'ixture supply valve consisting of a depending tube on said bell formed with an inturned flange at its lower end, and a stationary cone over which said lower end fits and attached to a support provided with openings and with a petrol outlet above said ring.

In testimony whereof I have hereunto set my hand in presence of two-subscribing witnesses.
